Consensus guidelines on management of oral potentially malignant disorders.

Oral cancer is usually preceded by oral potentially malignant disorders (OPMDs) and early detection can downstage the disease. The majority of OPMDs are asymptomatic in early stages and can be detected on routine oral examination. Though only a proportion of OPMDs may transform to oral squamous cell carcinoma (OSCC), they may serve as a surrogate clinical lesion to identify individuals at risk of developing OSCC.

Comprehensive Review on Synthesis, Properties, and Applications of Phosphorus (P, P, P) Substituted Acenes with More Than Two Fused Benzene Rings.

This comprehensive review, covering the years 1968-2022, is not only a retrospective investigation of a certain group of linearly fused aromatics, called acenes, but also a presentation of the current state of the knowledge on the synthesis, reactions, and applications of these compounds. Their characteristic feature is substitution of the aromatic system by one, two, or three organophosphorus groups, which determine their properties and applications. The (P, P, P) phosphorus atom in organophosphorus groups is linked to the acene directly by a P-C bond or indirectly through an oxygen atom by a P-O-C bond.

MSRSGC: A prospective study of heterogenous group atypia of undetermined significance.

Context: : Many standard books, literatures, and internet described the characteristic lineament of each salivary gland lesion. Nevertheless, there are dozens of disarray, confusion, and unmanageable morphological features regarding proper reporting. To fight with these issues, Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) was introduced in 2018, but still the third category, Atypia of undetermined significance (AUS), poses difficulties for the pathologists and clinicians for a definite interpretation.

Blended Ensemble Learning Prediction Model for Strengthening Diagnosis and Treatment of Chronic Diabetes Disease.

Diabetes mellitus (DM), commonly known as diabetes, is a collection of metabolic illnesses characterized by persistently high blood sugar levels. The signs of elevated blood sugar include increased hunger, frequent urination, and increased thirst. If DM is not treated properly, it may lead to several complications.

Evaluation of Root Dentinal Damage Associated with ProTaper Gold, WaveOne Gold, and ProTaper Next during Cleaning and Shaping Procedures: An Analysis.

Aim: The purpose of this study is to evaluate and compare the incidence of dentinal defects after root canal shaping using rotary nickel-titanium (Ni-Ti) instruments (ProTaper Gold [PTG] and ProTaper Next [PTN]) and reciprocating instrument (WaveOne Gold [WOG]).
